Who Killed Spirit?

Spirit Airlines shut down on May 2, 2026. Since then, people have argued about who is to blame. Some blame Lina Khan. Others blame Biden-era antitrust policy, Spirit's own leaders, Pratt & Whitney's engines, the big airlines, or a spike in fuel prices. The record points to more than one cause. Here is how each suspect holds up.

Suspect 1: Lina Khan

Khan chaired the Federal Trade Commission from June 15, 2021, to January 20, 2025, according to the FTC. She was one of the best-known faces of the Biden administration's tougher line on big mergers. That is why her name comes up.

But the FTC did not bring this case. The Justice Department's Antitrust Division sued in March 2023, along with six states and Washington, D.C. Even the Trump administration's Transportation Department, in its May 2, 2026, statement, blamed Joe Biden and Pete Buttigieg, not Khan. On the narrow question, the answer is no. Khan did not kill Spirit.

Suspect 2: The JetBlue merger block

This is the strongest case against Washington. JetBlue agreed in July 2022 to buy Spirit for $3.8 billion. On January 16, 2024, U.S. District Judge William G. Young blocked the deal. He ruled that it would substantially lessen competition in violation of the Clayton Act.

The judge's own ruling shows why the call was close. He found that Spirit expected a $467 million loss for 2023, on top of more than $1 billion in earlier losses. He noted it had not made a profit since 2019. He also wrote that the airlines gave "strong evidence" that the combined carrier would bring "substantial benefits for consumers."

He still ruled against them. Spirit's executives had testified that the airline had a plan to return to profit, and the judge found that JetBlue was "far from the only available purchaser." So the strict "failing firm" defense did not apply. He also described the "Spirit Effect," the pattern of fares falling when Spirit entered a route.

The two airlines ended the deal in March 2024. JetBlue agreed to pay Spirit $69 million to settle. Spirit's last CEO, Dave Davis, told CNBC that without the block, "I believe that we wouldn't be in the situation we are right now."

That claim can't be tested. By its own account, JetBlue was also working to get back to profit at the time. Still, the block closed off Spirit's clearest exit.

Suspect 3: Spirit's own choices

Spirit had another suitor first. It agreed to merge with Frontier, another low-fare airline, then ended that deal in July 2022 and paid Frontier $25 million. A day later, it signed with JetBlue, which had offered more. That bid always carried more antitrust risk.

Then came two bankruptcies. Spirit filed the first in November 2024. It emerged in March 2025 after turning $795 million of debt into equity. About five months later, it filed again. Spirit's own August 2025 release said the first round had been "targeted exclusively" on debt and new equity, and that "there is much more work to be done." By Spirit's own account, the first fix did not go far enough.

Suspect 4: Pratt & Whitney's engines

In July 2023, Pratt & Whitney found a flaw in the metal used for some engine parts. It told Spirit that nearly all the geared turbofan engines on its Airbus A320neo jets would need inspection or new parts, according to Spirit's filings. Spirit grounded some of its newest planes. Pratt's affiliate agreed to pay credits for the idle jets, worth an expected $150 million to $195 million for 2025 alone. Parked planes still cost money and earn nothing, and this hit Spirit during the same years it was fighting to survive.

Suspect 5: Big airlines and fuel

Davis also pointed to the big airlines. He said they copied Spirit's model with cheap basic economy fares, and that their credit card deals give them cash to ride out shocks. Spirit had no such cushion.

The final blow was fuel. Spirit reached a deal with its bondholders in March 2026. Then, according to its shutdown notice, a "sudden and sustained rise in fuel prices" left it needing "hundreds of millions of additional dollars" it could not raise. CNBC tied that fuel spike to the war in Iran. Talks on a federal rescue loan also fell apart.

The verdict

Lina Khan did not kill Spirit. Her agency never brought the case. The merger block is a fair suspect, because it removed Spirit's best lifeline at a weak moment. But a block in early 2024 did not cause a shutdown in May 2026 by itself. Engine groundings, a too-small first bankruptcy, bigger rivals and a fuel shock all did real damage along the way.

The honest answer is that Spirit had many wounds, and the merger block was one of them, not the only one.

What it means for travelers

Spirit is still selling off its assets in bankruptcy court. Spirit said card purchases would be refunded automatically, but credits, vouchers and Free Spirit points will be handled through the bankruptcy. JetBlue says it now runs the most flights at Fort Lauderdale, Spirit's old home base. It also offered a status match to Free Spirit Silver and Gold members for a limited time.
